a.活动烟罩不在操作位置时,氧枪不能下降。b.氧枪不在中心位置时不能下降。c.炉子正位连锁:炉子不在垂直位置时,氧枪不能低于V1点;而当氧枪低于V1点时炉子不能倾动。d.快速切断阀连锁:氧枪降到V2点下,如快速切断阀在10s内没有打开,氧枪自动提升。e.氧枪连锁:氧压低于额定值时(一般为0.4MPa),喷枪自动提升。f.水压水温连锁:冷却水压力(或流量)低于额定值时(一般为0.5MPa),氧枪自动提升;当进
a. When the active hood is not in the operating position, the oxygen lance can not be lowered. b. Oxygen lance can not be lowered when not in the center. c. Oven positive chain: the furnace is not in the vertical position, the oxygen gun can not be less than V1; and when the oxygen gun below V1 when the furnace can not be tilted. d. Quick cut-off valve chain: Oxygen gun down to V2, such as quick cut-off valve did not open within 10s, oxygen gun automatically upgrade. e. Oxygen gun chain: oxygen pressure is lower than the rated value (usually 0.4MPa), the gun automatically raised. f. water pressure water temperature chain: cooling water pressure (or flow) below the rated value (typically 0.5MPa), oxygen gun automatically upgrade;
